GRAIN HARVESTER.

Divided and this application led September 28, 1920. Serial No. 413,311.

T 0 all whom it may concern:

, Be it known that l, CHRISTIAN MAUL, a citizen of' the United States,residing at Batavia, in the county of Genesee and State of New York,havei invented new and useful Improvements in Grain Harvesters, oi'which the following is a specification.

rllhis invention relates to a grain harvester and more particularlytothe means for adjusting the upper elevator apron or belt, so that thesame runs parallel withv the companion lower elevator belt.

v.The object of this invention is to provide simple and efficient meanswhereby the upper elevator apronma'y be adjusted without taking oli theapron or otherwisepartly dismantling` the machine, thus saving time andlabor and avoiding undue interruption in the operation of theniachine.

vThisapplication is a division of an application. iiledby myself October17, 1919, Serial ANumber 331,417.

In the accompanying drawings:

Figure 1i is a rear elevation, partly in section, of a kgrain harvesterembodying` my improvements. Figure 2-isca fragmentary verticallongitudinal section of the machine. Figures 3'iand 11 are fragmentaryvertical sections taken on the .correspondingly numbered) lines in F ig.2. j l

Similar characters of reference indicate corresponding parts throughoutthe several views. Y l j 10 represents the main frame of the harvesterwhich may be of any suitable construction to support the several workingparts and which is supported on the stubbleward side by a master wheel1.1 and on the grainward sideby a vsupporting wheel 12.

VOn the grainward end of the frame is arranged a horizontal conveyerwhich receives the 'grain'from the cutter mechanism and delivers thesame to theelevator, whereby the grain is elevated over the master-wheel and presented to the lbinder mechanism whichpties bands aroundbundles of grain. This honlzontall conveyer is ot usual and well knownform and preferably comprises a canvas apron or belt 13 which passes atits grainward and stubbleward turns around supporting rollers 111, 15journaled on the main frame. This horizontal conveyor moves with itsupper operative stretch from the grainward side toward the stubblewardside of the machine and theV grain is directed' upon the same from thecutter mechanism by the usual rotary reel 16.

The elevator' comprises lower and upper inclined canvas aprons orbelts17, 18, which extend upwardly at an angle from the delivery turn of thehorizontal conveyer to the upper or receiving end of thedownwardlyinclined binder deck 19. The lower elevator apronypa'sses withits lower and upper turns around horizontal receiving and deliveryrollers 20, 21, which are journaled transversely on the lower and upperparts of the main irame, this apron being operated to move upwardly withits upper stretch. The upper elevator apron passes with its lower andupper turns around horizontal receiving and delivery 'rollers 22, 23which' are journaled transversely in two supporting bars'or plates 2st,25, arranged transversely and in an inclined' position'relatively to themain frame" at the front and rear' sides of the elevator. The lowerstretchof the upper apron moves upwardly, so that the grain dischargedfrom the horizontal conveyer will be receivedbeween the opposingstretches of the two elevator aprons and carried upwardly to the binderdeck. ln passing from the elevator aprons to the deck vthe' grain isengagedy by an intermediate clearing roller 26 which is journaledhorizontally and transverselyv on the main frame in the gap between theelevator and the deck.

As the grain slides down the binder` deck the same is receivedbetweenthe needle 27 and the knotter 28 of the bundling and tyingmechanism which is arranged adjacent to the lower part 1 of the deck andwhich may be of any suitable construction to tie bands around thebundles of grain which is' being harvested.l

The space or passageway between the elevator aprons is closed on thefront side ofn this space by" the adjacent walll 29 which is mounted onthe main frame andwhich faces the butt ends of the grain, asshown inFigs. 3 and 11', while the rear side of this space or passageway is openand forms a gap or throat 30 through which the heads of the grain ofvarying length project roarwardly therefrom. This necessitates mountingthe rollers of the upper elevator apron on a rearwardly overhangingsupplemental frame which is supported at its front side on the mainframe. vIn its preferred form this overhanging frame comprises the twolongitudinal side plates or bars 24, 25, which are arranged at the frontand rear sides of the elevator and on which the rollers of the upperapron are journaled and two horizontal tie rods 3l, 32 passingtransversely through the lower and upper ends of the side platesand'connecting the same with each other and with the adjacent Jfrontwall 29 of the inclined grain passage.

'lowing to. the overhang of the supplemental frame, means are providedfor adjusting the same in a plane parallel with the path of the grainthrough vthe elevator in order to maintain the rollers of the upperelevatorI apron parallel with those of the lower apron and cause theupper apron to run properly and most efficiently.l For this purpose Itherear end of the overhanging supplemental frame'is adjustably connectedwith the adjacent part of the main trame as follows:

' 33 represents an upright link which is engaged at its upper end with apin 34k on the upper part of the main traine, while its lower endengages with a projection on the upper part of the rear plate 25 oll thesupple mentalframe, which projection may consist ofthe upper tie .rod31, as shown in Figs. l

and l of the drawings, although a separate projection may be employed ifdesired.

This connection between the main frame and the rear vpart of thesupplemental trame permits the upper elevator apron and associated partsto rise and fall in vadapting itself to variations in the thickness ofthe mass of grain which is being harvested and also permits the rear endof the supplemental trame to be freely adjusted parallel with the pathof the grain through theelevator for obtaining proper ruiming of theupper elevator apron.

.Thepreferred means for effecting this adjustment of the supplementalframe comprises a shifting rod 35 arranged lengthwise of the rear plate25 of the supplemental frame and connected at its lower end with thisframe by a pin 36, as shown in Fig. l, or by other suitable means, aperforated bracket 37 secured to the upper part of the main frame andreceiving the upper end of said shitting rod, and screw nuts 38, 39applied -to the threaded upper end of said rod and engaging with theopposite sides of the bracket 37. Upon loosening one of the screw nuts38, 39, and tightening the other, the

shifting rod and the rear part of the supplemental frame are moved up ordown parallel with the path of the grain through the elevator. By thismeans the upper elevator apron can be adjusted so that the same runstrue to the lower elevator apron while the machine is running andwithout requiring the operator to reach into the interior of the machineor taking off any of the canvas aprons, inasmuch as the adjustingdevices for this purpose are on the exterior of the machine. Thisadjustment of the rear part 25 of the supplemental frame is permissibleby reason of the fact that the same is movably connected with therelatively stationary front part 24 of this frame by the rods 3l, 32

and other connections which yield Vsuiiiciently to enable the rear plate25 and the bearings therein for-the rollers 22, 23 to be adjusted as maybe necessary. In Fig. 4 the two rollers of the upper elevator apron arerepresented by dotted lines in a position in which the supplementalVframe vhas sagged out of its normal position while the full lines showthe same restored to the proper position by the adjustingI device. v

I claim as my invention:

1.'A harvester, comprising a main frame, an inclined elevator having aVsupplemental frame which is supported at its front side on the mainframe and has its rear side arranged underneath a part of said maintrameand means for adjusting said supplemental frame parallel with thedirection in which the material is propelled by said elevator comprisinga shifting rod arranged length- 'i Wise of the'dirction in which thematerial is moved by the elevator and connected at its lower end withthe lower end of said supplemental frame on the rear side of the same, abracket arranged on the upper end of the main frame above thesupplemental frame, and screw nuts arranged on the upper vend of saidrod and engaging opposite sides of said bracket.

y2. A harvester comprising a main iframe,y an elevator having asupplemental frame which is supported on one side on said main frame,and a guide link connected at its upper and lower ends with said mainand supplemental frames and capable of swing-- ing lengthwise of thelatter and permitting the same to rise and fall and also move lengthwiseof the direction in which the ma terial is propelled by said elevator.
